Understanding the Mechanics of Network Loops The primary cause of a loop is physical redundancy, which is intentionally designed into networks for reliability. This results in a spike in CPU utilization as the switch struggles to process the torrent of traffic, effectively freezing the network for legitimate communication.

Instead, the frame is sent back to the switch that originally sent it, creating a reflection that multiplies with each pass. Avoid connecting multiple switch ports to the same network segment accidentally.
While physical redundancy is essential for high availability, it must be managed by robust layer 2 protocols to prevent chaos. Implement a robust network monitoring system to detect traffic anomalies.

With each iteration, the number of frames doubles, overwhelming the buffer memory of the devices. Switches flood unknown unicast frames to all ports, and because the loop exists, these frames return to the switch repeatedly.
